Abstract: In a time-division duplex (TDD) system, a reliable initialization scheme that is applicable to an automatic gain controller (AGC) at a base station is implemented in various forms depending on the availability of certain information such as signal-to-interference ratio (SIR), spreading factors and other parameters. A more accurate estimation of the initial control word of a gain-adjustable amplifier for one or more time slots is implemented. The scheme is applicable to AGC initialization for each time slot of the TDD system, but is also applicable to other systems of transmission, without limitation.

Abstract: A wireless communication method and apparatus for decoding an enhanced uplink dedicated channel (E-DCH) absolute grant channel (E-AGCH) transmissions are disclosed. A wireless transmit/receive unit (WTRU) receives E-AGCH data which includes a cyclic redundancy check (CRC) part and a data part. The CRC part is masked with a WTRU identity (ID) at a Node-B. The CRC part and the data part are demultiplexed and the CRC part is demasked with the WTRU ID. A CRC is then performed with the demasked CRC part. If the CRC passes the data part is sent to an enhanced uplink medium access control (MAC-e) entity. The WTRU ID may be a primary E-DCH radio network temporary identity (E-RNTI) or a secondary E-RNTI. When the E-AGCH data is transmitted over a 10ms frame, if the CRC fails, E-AGCH data via subsequent subframe may be soft combined with the previous E-AGCH data.

Abstract: A wireless communication method and apparatus for detecting and decoding enhaiced dedicated channel (E-DCH) hybrid automatic repeat request (H-ARQ) indicator channel (E-HICH) transmissions are disclosed. A wireless transmit/receive unit (WTRU) receives E-HICH transmissions (202) and detects an H-ARQ indicator transmitted via the E-HICH by performing a binary hypothesis test (204). The WTRU then generates an acknowledgement (ACK) message or a non acknowledgement (NACK) message based on the detected H-ARQ indicator (206). A reliability test may be further performed to improve performance, whereby the binary hypothesis test may be performed only if the reliability test is passed.

Abstract: A method and apparatus for automatically correcting the frequency of a local oscillator of a receiver. A primary common pilot channel (CPICH) code sequence is generated by a CPICH code generator based on a reference cell identification signal and a frame start signal. The received despread CPICH code sequence is used to generate an estimated frequency error signal. A control voltage generator based on the estimated frequency error signal generates a control voltage signal. The CPICH code generator generates the CPICH code sequence based on signals received from a high speed downlink packet access (HSDPA) serving cell when HSDPA is active, or a timing reference cell when HSDPA is not active. The present invention achieves full maximum ratio combining gain when space-time transmit diversity (STTD) is used, even without receiving a transmit diversity indication.

Abstract: A wireless communication method and apparatus for generating a scheduling grant based on a relative grant are disclosed. A wireless transmit/receive unit (WTRU) receives an absolute grant from a serving radio link set (RLS) and receives a relative grant from the serving RLS and at least one non-serving radio link (RL). The WTRU decodes enhanced dedicated channel (E-DCH) absolute grant channel (E-AGCH)E-AGCH signals to detect an absolute grant, and decodes E-DCH relative grant channel (E-RGCH)E-RGCH signals to detect at least one relative grant. The WTRU then calculates a serving grant based on the detected absolute grant and/or the relative grant(s). The relative grant may be detected by performing a hypothesis test on the E-RGCH signals. A multiple alternative hypothesis test is performed for detecting the E-RGCH signals from the serving RLS and a binary hypothesis test is performed for detecting the E-RGCH signals from the at least one non-serving RL. A reliability test may be further performed on the E-RGCH signals.

Abstract: An adaptive equalizer including an equalizer filter and a tap coefficients generator used to process a sample data stream derived from a plurality of received signals is disclosed. The tap coefficients generator includes an equalizer tap update unit, a vector norm square estimator, an active taps mask generator, a switch and a pilot amplitude reference unit used to minimize the dynamic range of the equalizer filter. A dynamic mask vector is used to mask active taps generated by the equalizer tap update unit when an unmasked signal output by the equalizer filter is selected by the switch to generate an error signal fed to the equalizer tap update unit. A fixed mask vector is used to mask active taps generated by the equalizer tap update unit when a masked signal output by the equalizer filter is used to generate the error signal.

Abstract: A method and apparatus for compensating for phase noise of symbols spread with a long spreading code are disclosed. To compensate for the phase noise, a phase error estimate is generated from despread symbols with a short spreading code. A phase correcting phasor is applied to chip rate data before despreading the data with a long spreading code. A signal-to-interference ratio (SIR) on a common pilot channel (CPICH) may be calculated by spreading the data with a parent spreading code in an orthogonal variable spreading factor (OVSF) code tree and by combining symbols. Alternatively, a magnitude of the symbols may be used in estimating the SIR. The SIR of a channel using a short spreading code and an SIR of a channel using a long spreading code are measured. The SIR of the channel with the long spreading code may be compensated in accordance with a difference between degradation of the SIRs.

Abstract: A receiver which suppresses inter-cluster multipath interference by processing an impulse channel response consisting of two multipath clusters, each cluster having groups of signals with multiple delays. In one embodiment, the receiver includes a single antenna and parallel-connected delay units used to align the groups of signals before being input into respective sliding window equalizers. The outputs of the equalizers are combined at chip level via a combiner which provides a single output. In another embodiment, a Cluster Multipath Interference Suppression (CMIS) circuit is incorporated into the receiver. The CMIS circuit includes a hard decision unit and a plurality of signal regeneration units to generate replicas of the multipath clusters. The replicas are subtracted from the respective outputs of the delay units and the results are input to the respective sliding window equalizers. In another embodiment, multiple antennas are used to receive and process the clusters.
